Research on Evaluation Method of the Bridge Strengthening Effect Based on Fiber Optic Sensor

Abstract:

A new evaluation method of the bridge strengthening effect is proposed based on the fiber optic sensor. The monitor layout scheme of bridge is designed to monitor the bridge strengthening effect accurately by measuring dynamic load moment and transverse vibration of the railroad bridge using the fiber Bragg grating sensor. At first, the paper presents the evaluation principle of the bridge strengthening. And then the fiber sensors are set up on the railroad bridge for extracting data of the health status from these sensors. The effect of the strengthening could be shown from the data change after bridge strengthening applied. The researches provide the scheme of the bridge strengthening quality evaluation, which is the base for the control of construction quality for new bridge strengthening technology.
